HEADLIGHT Filed May 9, 1933 flbel/Va/ira BY ATTORNEY Patented May 15,1934

UNETED STATES PATENT FFEQE 1 Claim.

This invention relates to vehicle headlights, and its general object is to provide an anti-glare device in the form of an attachment for any type of headlight and which will permit the use of a clear lens and bulb with the usual parabolic reflector so as to provide maximum light where needed, without the accompanying glare.

Another object of this invention is to provide an anti-glare attachment for a headlight, that can be installed in any headlight, in an easy and expeditious manner, is simple in construction, inexpensive to manufacture, and eflicient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinaiter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a front elevation showing the application of my device to a headlight.

Figure 2 is a vertical sectional View taken through a headlight having my device installed therein.

Figure 3 is a detail sectional view showing one of the side clamps of my attachment in use.

Figure 4 is a perspective view of a side clamp.

Figure 5 is a similar view of the center or intermediate clamp.

Referring to the drawing in detail, the letter A indicates a headlight having the usual reflector B to which is attached the device which forms the subject matter of the present invention, C indicates the headlight bulb and D the lens.

My device includes a substantially semi-circular translucent plate 1 which may be frosted or ground glass, but in any event is shaped to have a curved rear edge to follow the curvature of the reflector B,'while its front edge is straight and the plate is secured in the reflector at an inclination above the headlight bulb C and in a parallel substantially V-shaped ears 3 which together with the body 2 are relatively flat, and the ears 3 are adapted to embrace the forward portion of the plate 1 at the ends thereof, with the forward edge contacting the body 2 as clearly shown in Figure 2.

The side clamps are formed from bendable metal and the body portions 2 thereof are passed through slots arranged in diametrically opposite sides of the reflector B. The bodies 2 are then bent about the flange of the reflector as best shown in Figure 3, with the result the side clamps will be held rigidly associated with the reflector and against casual displacement as will be apparent.

The center or intermediate clamp includes a base plate 4 that has formed thereon and extending at an inclination therefrom spaced parallel substantially semi-circular ears 5 for the purpose of receiving the rear edge of the plate 1 midway its ends as best shown in Figure 1, and secured to the base plate 4 is a threaded stud 6, the latter being adapted to receive a washer '7 and a nut 8, when the threaded stud is inserted through an opening formed in the reflector B as clearly shown in Figure 2. It will be noted that the washer '7 is substantially wedge shape so as to follow the shape of the reflector, and as the base plate is inclined, it will be apparent that the center clamp can be rigidly fixed with respect to the reflector.

From the above description and disclosure of the drawing, it will be obvious that as the plate 1 is translucent and is disposed above the headlight bulb C and directed downwardly toward the forward end of the headlight, with its forward edge slightly below the focal point of the bulb, that a glare will be impossible, yet ample light will be directed toward the front of the headlight to illuminate the roadway directly in front of the vehicle carrying the same.

In view of the fact that my device permits the use of clear lens and light bulbs, with the usual parabolic reflector, it will be further obvious that maximum light will be provided where needed without glare.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

thereto, a center clamp including a base plate, spaced parallel ears formed with the base plate and extending at an inclination therefrom for receiving the rear edge of the translucent plate, a threaded stud extending from the base plate and passed through the reflector, a substantially wedge shaped washer following the shape of the reflector and received by the stud, and means on the stud for securing the center clamp to the reflector.

ABEL MOLNAR.
